Abstract
A novel metabolite of FK-506-a C13, C15, C31 O-demethyl C19 hydroxymethyl C36 isomerized epoxide of FK-506 obtained from erythromycin-induced rabbit liver microsomes--was isolated by HPLC and identified by FAB/MS and NMR. The existence of ring-chain tautomers for this metabolite is demonstrated by NMR spectroscopy. FAB/MS, and HPLC.Entities:
